Fun fact about Buzz's "girlfriend"
People have always laughed their asses off with that scene, where Kevin is going through his brother's private stuff, and he finds a photo of a fat, ugly girl with a crazy, bug-eyed smile, and he says, "Buzz, your girlfriend--woof!"
That was actually one of the director's sons dressed up as a girl for the photo, because he couldn't bear for anyone to say that about a real girl on camera.
